As already posted to the list, I have been working to change most of the tags to
generate indexed names within an iterate loop, for just this kind of situation.
I have just changed the code for submit, so that the index of your iterated
collection is added to the name ie name="submit[0]" etc. In your action you can
then check which button was pressed, and display details for this record.
Avoids javascript!
I am attaching an updated zip file to include this. When I get some time, I
will post all this to the dev list, to see about getting it added to Struts.
Instructions as per previous posting:
Instructions for use:
- unpack attached zip file (this mailing list only accepts messages < 100K!!)
and copy .java files to ../org/apache/struts/taglib/html/
- rebuild struts
- add the struts-html.tld to your WEB-INF directory
- within an iterate tag, simply add "indexed=true" to the tag you wish to use.
Eg to produce the text tag
<input type="text" name="parameter[0].value" value="Mac">
use:
<logic:iterate id="parameter" name="ParametersForm"
property="parameterList">
...
<html:text name="parameter" property="value" indexed="true"/>
...
</logic:iterate>
[in this case, simply do: <html:submit indexed="true">
Hope this helps,
Dave

Subject: Re: How can I pass extra information on Submit button?
You could place the id in the name of the submit button... Then the action
could parse the name of the submit button that was pressed for the id....
There must be a better method than this... But I have not come across this
before, and that is what popped in my head.
Or.. If you can use javascript, you can set the form action (with the id) and
submit the form with a simple javascript call.
However, you must be able to gaurentee that all users will have javascript
enabled.
We do this... (But we are able to force our users to enable javascript)
